High Voltage Composite Deadend Suspension Type Insulators

It is especially used in dirty areas, can effectively prevent the dirt flash accident, is currently widely used porcelain insulator alternative products.

Composite insulators, also known as synthetic insulators, its main structure by the umbrella skirt sheath, epoxy glass fibre (FRP) mandrel and end of the three parts of the fittings. The umbrella skirt sheath is made of high-temperature vulcanised silicone rubber, the FRP mandrel is a glass fibre reinforced material, epoxy resin as the matrix of FRP composite material, and the end fittings are carbon cast steel or carbon structural steel coated with hot-dip galvanised layer on the outer surface.

Composite insulators of this structure will be mechanical strength and external insulation performance separately, the core rod and skirt sheath respectively bear mechanical and electrical loads, thus integrating the skirt sheath materials to withstand the atmosphere, aging performance is superior and the core rod material tensile mechanical properties of the advantages of good. As part of the insulator structure, the fittings mainly play the role of transferring mechanical stress and connecting and fixing.
